Y IMPROVED BRICK MACHINE.

@te .rlpnrlefnfemh irrin'tlgce ttrtters rtsut .nu mating am lai it una TO ALL WHOM IT MAY CONCERN:

Be it known that we, J. and C. C. McDRMID, of Cambria Mills, in the county of Hillsdale, and Sta-tc4 of Michigan, have invented a certa-in new and useful 'improvement on Brick Machines, .of which the following is a full, clear, and exact description, reference being had tothe accompanying drawings, forming part of this specification, and in which- V Figuresl and 2 represent elevations at right angles to each other of a brickmachine constructed according to our improvement.` v

Figure 3, a vertical section of the -sam'e ina-plane or planes parallel to iig. 2; and

Figure 4, an inverted plan of a double cam or wheel with double inclineson its face, for, iu conjunction with weights or weighted levers, operating the plunger and mould-box pusher. t Like letters of reference indicate corresponding parts.

The nature of our invention consists, firstly, in anovel combination of a positive motion to the raising of the plunger, with a free weighted action to the pressing action of the saine. Also, to a controllable adjustability of such weight to regulate the pressing force of the plunger. And said invention further consists in a similar positive and free orV independent weighted action for actuating the moulds, -pushing frame, and novel gear or connection of devices for accomplishing the same through aseparate weight, whereby the action ot' the pusher is automatically arrested on the fouling cr sticking of a mould. i

y Referring to the accompanying drawing,A is the grinding-mill, which may either be carried by the same 0r a separate frame 'to that ofthe press-box with its appurtenances. B is the mill-shaft, that may be driven by vany suitable power, and provided with the usual or other grinding or forcing-knives, not necessary here to be represented or described. C is a wheel o r attachment to the vertical revolving mill-shaft B, forming on itsrunder face a circular track or tracks, a, with cam or inclined projections b c thereon, foroperating, in conjunction with weights or weighted levers, the plunger or follower to the press-hoxand pusher or pushing frame to the moulds, the cam projections b c, and'track or tracks they are arranged upon, serving as it'werc to control the lifting action of the plunger and advance stroke ofthe pushing frame, and secure to such devices their proper relative i operations and pauses, while the weight or weighted leversiserve to give the pressing stroke to' the plunger and return motion to the pushing frame, essentially as hereinafter' described. D is the moulding or pressing-box, which may be of wood, and made to rest upon an iron grate or clod-cutter, ci, the same being suitably stayed or supported, no particular reference to the construction of the framework here being considered necessary. E is the follower or plunger, worked by a lever, e, which is connected by a rod,f, with a lever, F, that: is hung on'a fulcrum, as at g, and carries on its inner or back end aroller, h, which bears against the outer portion of the trackV a ofv the wheel C and outer cam projections b, while said leverF carries at its outer or front end a. weight, G, attached `to a slide, 2', arranged to admit of itsadjustment on or along theY lever F, and controlled, it may be, by a rod, j, attached to a lever, 1,'having its fulcrum as at k, and operatedvby a rod, Z. This arrangement serves lto give to the plunger, by weight as distinguished from pressure, its requisite power to force the clay into the mouldinand thispower is made readily controllable bythe movement of the weight G closer to or further from the fulcrum g as effected by the lever I, which may be connected to the slide z' at any one of a series of holes m in the rod j for the pin uniting said rodj with said lever I, and also by a notched construction, as at n, of the rod Z, held by a locking staple or other device, o, and secured, it. may be, by a lgeyd). By these means any desired amount of pressure may he applied to' the clay in the .moulding-box, and changed -withfacilityand dispatch should the pressure be either too` little or excessive. similar principle of action is made to govern the pushing frame J, which. serves to give the moulds or mould frame K its or their advance movement under and from beneath the grate d. Thesemould frames are or may b e fed in at one side or end of the machine to lie in front of the pusher J, which latter each advance movement moves said mould frames in succession beneath the grate d, where they may rest on rollers q. The means for accomplishing this are or may be as follows: L is a rock. shaft, carrying arms r thatare connected'with the pusher J, and by means of an outside arm or lever, s, with s rod, R, which isprovided near its upper end with a shoulder, t, on which rests a lever, M, having its fulcrum as at u, and bearing' by a roller, v, aganst'the inner portion of the track and cam projections c of the wheel C by means of a weight, N, which projections a under such an arrangementbecome the driver or power to give tothe pushing frame J its advance movement. As it is necessary, however, to provide against a mould frame fouling or getting fast on putting it into the machine, the lift of the rod R with the front portion ofthe lever M is e'ected by means of a weight, O, connected by oord or chain w and suitable pulleys or guides x with the rod. This gives a freedom to the rodR, under control of the Weight O, irrespective of the lever M and weight N, which, in case of any fouling of the moulds or mould frames, arrests in an automatic manner' motion of thelattcr by the pusher J, till, say, the lever M again lowers, when the mould frame may be properly put in.v P is a striker, bevelled on front and in rear at its bottom edge, and kept down by weights 1/ at each end, and arranged Ain front ofthe clod-cutter to clear the moulds of surplus clay as they are delivered by the pusher J inits advance stroke. i

I What is here claimed asl new and useful, and desired to be secured by Letters Patent, is-

1. The combination, with a positive or cam-like action to the lever F, which controls the m'otion of the follower, of erw-eight to saidlever arranged to give pressingrpower or force to the follower on reliefI of the lever from its positive lifting action on the follower, substantially as specified.

2. The combination, with the lever F, ofthe adjustable o r sliding Weight G under control of a leveryI, and rod Z, or their equivalents, essentially as and for the purpose or purposes herein'set forth.

3. The pusher prpushing frame J, actuated by a cam-like or positive action in its advance stroke, and by a weight o r weighted lever in itsreturu stroke, substantially as specified.

4. The gear ofthe rod R, which actuates the pusher J, with the weighted lever M in a loose or indcpen dent manner, under control ofaweight, O, essentially as and for the purpose herein set forth.
